Why Choose US
We test leakage of each roll before braiding, then we cut 300mm and crimp it to test
burst pressure after brading.
We use CNC Lathes Machine for end fittings production. Machine system, knife and inspection
tools are all imported from Japan.
We use Techmaflex Crimping Machine which is imported from France. This machine has
accurate and stable performance for crimping because it is produced for PTFE hose crimping only.

Diagnosing and Troubleshooting Rubber Coupling Issues
Diagnosing and troubleshooting problems with rubber couplings in machinery systems involves a systematic approach:
- Visual Inspection: Check for signs of wear, cracking, or deformation in the rubber elements.
- Vibration Analysis: Monitor vibration levels using sensors to identify excessive vibrations or irregular patterns.
- Noise Assessment: Listen for unusual noises during operation, which could indicate misalignment or worn components.
- Temperature Check: Monitor the operating temperature of the coupling, as overheating might indicate issues.
- Alignment Check: Ensure proper alignment between connected shafts to prevent excessive stress on the coupling.
- Torque Measurement: Measure the transmitted torque to identify any discrepancies from the expected values.
- Dynamic Testing: Conduct dynamic tests with load variations to identify performance issues.
- Comparative Analysis: Compare coupling behavior to baseline performance data.
If any issues are identified, they should be promptly addressed through proper maintenance, realignment, or replacement of damaged components.
Handling Torque and Vibration Suppression in Rubber Couplings
Rubber couplings are designed to effectively handle both high levels of torque transmission and vibration suppression. The flexibility and damping properties of rubber make it well-suited for these purposes:
- Torque Transmission: Rubber couplings can transmit torque between shafts while accommodating angular misalignment. The rubber element flexes and deforms as torque is applied, allowing the coupling to transmit power even in misaligned conditions.
- Vibration Suppression: Rubber’s inherent damping characteristics help absorb and dissipate vibrations and shocks generated during the operation of machinery. This feature reduces the transfer of vibrations to connected components, minimizing wear and enhancing overall system performance.
Engineers select the appropriate rubber material and coupling design to ensure that the coupling can effectively handle the required torque levels and provide the desired vibration suppression. Rubber couplings find applications in various industries where torque transmission and vibration damping are critical for smooth and reliable machinery operation.
Factors to Consider When Selecting a Rubber Coupling
Choosing the right rubber coupling for a specific application involves considering various factors:
1. Torque Requirements: Evaluate the torque that needs to be transmitted between the input and output shafts. Select a coupling with a rubber element that can handle the required torque without exceeding its limits.
2. Misalignment Compensation: Determine the degree of misalignment (angular, axial, and radial) present in the system. Choose a rubber coupling with appropriate flexibility to accommodate the expected misalignment while maintaining efficient torque transmission.
3. Vibration Damping: Assess the level of vibrations and shocks in the application. Opt for a rubber coupling with effective vibration-damping properties to protect the machinery and enhance its reliability.
4. Service Environment: Consider the operating conditions, including temperature, humidity, exposure to chemicals, and potential contaminants. Select a rubber material that can withstand the environment without deteriorating.
5. Shaft Sizes: Ensure that the coupling’s bore sizes match the shaft diameters of the connected equipment. Proper shaft fitment is crucial for efficient torque transmission.
6. Maintenance Requirements: Evaluate the maintenance practices of the system. Some rubber couplings may require periodic inspection and replacement due to wear over time.
7. Cost and Budget: Factor in the budget constraints while choosing a suitable rubber coupling. Balancing performance and cost is essential for an optimal solution.
8. Application Type: Different industries and applications have unique requirements. Choose a coupling type (spider, jaw, tire, etc.) based on the specific needs of the application.
By carefully considering these factors, you can select a rubber coupling that provides efficient torque transmission, vibration isolation, and durability in your mechanical system.
